Title: Safety emergency-off switching for contactor feeders with an upstream power circuit breaker
Inventor: BAERNKLAU KARL-HANS DIPL ING
IPC: H01H47/00
Filed: 1988-05-05
Abstract: Conventional emergency-off devices for main circuits have until now been implemented by redundant design of the motor contactors. This is highly cost intensive, labour intensive and occupies a large amount of space, since the main current paths of the contactors in this case have to be connected in series. The present invention makes use of the fact that a power circuit breaker is connected upstream of the motor feeders in most cases. The undervoltage trip device of the power circuit breaker is thus used for emergency-off switching. To this end, the coils of the contactor feeder have timers connected in parallel with them, whose contacts (which open in a delayed manner in the event of a voltage failure) are connected upstream of the undervoltage trip device, with a normally-closed contact (break contact), which is connected in parallel therewith, of the associated contactor. Emergency-off switching in the case of distribution networks.

Inventor: HACKETT ANDREW
IPC: H04N11/04
Filed: 1988-11-15
Abstract: PCT No. PCT/EP89/01327 Sec. 371 Date Jul. 1, 1991 Sec. 102(e) Date Jul. 1, 1991 PCT Filed Nov. 7, 1989 PCT Pub. No. WO90/06037 PCT Pub. Date May 31, 1990.A system to facilitate mixing and recording video signals of different standards, e.g., in digital format via a digital video recorder, is disclosed. A first video signal in progressive scan format is converted to a standard format (e.g., line interlaced) prior to recording. A standard second video signal (e.g., line interlaced) is predistorted without format conversion prior to recording with the first signal to reduce artifacts associated with post-processing after recording. The predistortion involves vertically displacing selected picture elements. Before being displayed, a video output signal from the recorder is converted to the scan format of the first video signal.
Patent DE-3839974-A1 (DE)
Title: Curved escalator
Inventor: BRUNN ERIK DIPL ING
IPC: B66B21/06
Filed: 1988-11-26
Abstract: To construct circular curved escalators, it is necessary to compensate for the different angular velocities of step inner edge and step outer edge occurring in the transition area and in the landing zones, since dangerous gaps will otherwise occur between the individual steps. The invention avoids these gaps owing to the fact that steps and chains in the transition areas and landing zones cover different distances so that, despite variable horizontal path velocities, the angular velocity on the inner path and outer path is identical. The steps and chain are designed in such a way that a horizontal displacement of the chain under the step is possible during the movement, as a result of which the chain covers a different distance to the step.

IPC: A61F5/01
Filed: 1989-04-07
Abstract: Patients with a walking impediment, especially those having a very severe walking impediment, have hitherto moved about in a wheelchair which, however, is very difficult to handle in narrow spaces. Furthermore, wheelchairs have a very elaborate design, so that their production is expensive. The invention is intended to create a device which improves mobility in narrow spaces and which is cheaper to produce. According to the invention, the device comprises a chassis (1) having four wheels (4, 5), two of which are in each case connected to one another via axles (2, 3). One axle (2) is fixed off-centre on the wheels (4), fixation on one wheel (2) being offset by 180@ relative to the other wheel (2). Moreover, the chassis (1) has a linkage (6) fastened on cuffs (7) or the like fixed to the legs or the trunk of the patient with a walking impediment. By shifting the weight of the patient standing on the chassis (1), movement is possible, the weight always being shifted towards the wheel at which the axle (2) assumes the highest position. The device permits movement of patients with a walking impediment even in narrow spaces. Due to the simple design the production costs are low. <IMAGE>
